When it does get below freezing and there is - it's cold enough for ice to form, then that changes the whole landscape, and it makes the landscape a different landscape to the one that I worked with previously. And I want to understand that. But the big tension of the ice works is that they're often made when it's cold enough to freeze one piece of ice to another.

I'm not a performer, in that I don't like the public, but I work in that respect.

I soon realised that what had happened on a small scale cannot necessarily be repeated on a larger scale. The stones were so big that the amount of heat required was prohibitively expensive and wasteful.

If I had to describe my work in one word, that word would be time.

Stones are checked every so often to see if any have split or at worst exploded. An explosion can leave debris in the elements so the firing has to be abandoned.

Everything has the energy of its making inside it.

I am not a performer but occasionally I deliberately work in a public context. Some sculptures need the movement of people around them to work.
